Research on excellent solutions for intelligent energy-saving monitoring system of LED lamps

　　Urban street lighting is an indispensable public facility in people's daily life. It is understood that the current power consumption of street lighting in my country accounts for about 15% of the total power consumption. Faced with the tense situation of power supply, manual control and street light inspection have become an indispensable practical work, and it is also a work that requires a lot of manpower and material resources. The existing traditional power-saving measures are only achieved by turning off lights at intervals at night, adjusting the switching time of street lights, and turning off landscape lighting when power is tight. The methods are simple and have little effect. On the road of exploring LED street lights in the country, it is even more necessary to explore its unique LED control system in combination with the characteristics of LED street lights.

　　It is understood that there are very few solutions for LED driver power management and intelligent energy-saving monitoring of LED lamps in the market.

　　Secondary energy-saving monitoring system with obvious advantages

　　If intelligent control and management are fully implemented for street lights, tunnel lights, square lights, industrial lighting, etc., more than 80% of manual inspection costs will be saved, so there is a strong market demand in the LED industry.

　　First, save energy and money.

　　Take 150W LED street lights as an example; pole spacing: 30m/pole, bilateral symmetrical lighting arrangement, 66 street lights per kilometer; daily dimming time:

　　Regarding the energy-saving effect of the system, for the sake of intuitiveness, the R&D department of Maoshuo made a calculation:

　　“Increased investment cost per kilometer (batch): 66 lamps × 90 yuan (power carrier module, concentrator) = 5940 yuan;

　　Additional investment cost for 10 km (in batch): 660 lamps × 90 yuan (power carrier module, concentrator) = 59,400 yuan;

　　Annual daily maintenance service fee for each lamp: 50 yuan;

　　Electricity savings per kilometer per year: 66 lamps × 0.31 yuan × 365 days = 7467.9 yuan;

　　10 kilometers saves electricity cost per year: 7467.9 yuan x 10 kilometers = 74679 yuan. "

　　Second, a quick maintenance guarantee mechanism service can be implemented.

　　Since LED street light faults can be diagnosed remotely and quickly, and local service personnel respond, the average maintenance time control MTTR is less than 8 hours, and the municipal street light management department actually feels that the LED street lights are working normally every night. "

　　Third, it is to protect users’ early investments.

　　The existing system can be directly upgraded to an intelligent street light control system by adding a power carrier module to the power supply to avoid repeated investment. In addition, the system is adaptable to future energy-saving upgrades by street light management departments, such as adding LED street lights, and can directly realize remote control dimming functions to avoid secondary renovations.

　　Fourth, adopt DALI protocol communication technology to achieve energy saving, environmental protection, multi-function, high reliability and intelligent management.

　　This solution product is designed around the goals of energy saving, environmental protection, multi-function, high reliability and intelligent management. It adds the development of the "DALI protocol-based intelligent control of lamp work" function, innovatively adopts DALI protocol communication technology in traditional power supplies, and remotely monitors each LED street light through independent communication lines, thereby realizing intelligent management of LED street light switches, dimming, brightness feedback, status query, fault alarm, group control, etc., achieving the purpose of further saving electricity and increasing the service life of LED lights. In terms of lighting usage time, the power consumed by the intelligent control LED system is about 3/4 of the power consumed by non-intelligent LEDs or even lower.
